sinusoidal
Like smooth waves
Sinusoidal describes anything having the form of a sine wave—the smooth, repeating S-curve that oscillates above and below a center line.
The term appears most often in mathematics, physics, and engineering: sinusoidal oscillation, sinusoidal signal.
Alternating current follows a sinusoidal pattern.
More loosely, sinusoidal can describe any wavelike or undulating motion.
